A preliminary evaluation of phenotypic traits of tepary bean (Phaseolus acutifolius A. Gray)

Abstract

(SRL) and shoot dry weight (SDW), respectively. A highly significant ( p < 0.01) positive association was observed between the shoot fresh weight and the SDW suggesting that there was a strong linear relationship between the two parameters. Similarly, at least 68.0 % of the changes in root dry weight were attributed to the changes in the SRL. Conclusion: These results suggested that the observed phenotypic variability in this germplasm which could be exploited for the enhancement of tepary bean. Contribution: There will be merit in validating these results on a field basis together with grain yield evaluation and genotyping over multiple locations and seasons to determine elite germplasm for production and utilisation by growers.
